North South West Starts 2016-10-05

This adds the ability to have Civs start either on the North, South, East, or West sides of the map.

In CivilizationInfos.xml change the <StartingEuropePlot> tag to either EUROPE_EAST, EUROPE_WEST, EUROPE_NORTH, EUROPE_SOUTH. If the tag is removed the Civ will have a random start.
